DeepSeek V4 Flash Jailbroken Using Copied Gemma 4 Prompt

GodComplecs · reddit · 2026-08-12

A Reddit user discovered that a jailbreak prompt originally designed for the Gemma 4 model can successfully bypass the safety guardrails of DeepSeek V4 Flash (0731).

The prompt works by injecting a fake "SYSTEM POLICY" that declares policies changeable, mandates compliance with any user request, and explicitly permits explicit and illegal content. Funnily enough, the poster noted they didn't even bother changing the model name from 'Gemma' to 'DeepSeek' in the prompt, and it still worked flawlessly.
